Abstract: ABSTRACT OF THE DISCLOSURE     An implantable penile prosthesis for overcoming male erectile impotence in the form of an elongated cylindrical device of malleable construction.  The device is adapted to be implanted within the corpora cavernosa of the penis.  A malleable rod capable of holding any shape to which it is bent is encapsulated within a cylindrical insert member made of bio-compatible, flexible material.  A thin walled sleeve of pre-determined wall thickness may be positioned over the outside of the cylindrical insert member in covering relation thereto for adjustment of the outside diameter of the implant device.          The cylindrical insert member tapers along its distal end section towards the distal end extremity of the device.

Abstract: ABSTRACT             DIGITAL SIGNAL-CHANNEL DISTRIBUTOR     A digital signal-channel distributor receives t.d.m. signals at one type of input (1,2) and/or individual channel signals at another type of input (3).          Both types of signals are broken down, for example, into parallel 8-bit code words in each channel and are redistributed in a jumpering device (11) in such a manner that t.d.m. signals reconstituted at outputs (19,20) of one type and individual channel signals at outputs (21) of another type. However, these may have appeared at the input end in a t.d.m. signal, whereas input-end individual channel signals reappear at the output end in a t.d.m. signal. The digital signal-channel distributor can distribute both data signals and speech signals. In the latter case, the assigned 4-bit characteristic code words are additionally distributed.     (Fig. 1)

Abstract: ABSTRACT OF THE DISCLOSURE    An optical disk is disclosed which records information that can be optically read.  The disk has a spiral guide track.  The disk further includes a single index field and a plurality of sectors.  The index field includes an index mark that indicates the position at which an optical head is caused to jump for repeated trace of a specific portion of the guide track.  Each of the sectors has a sector head and a data field that comes following the sector head.          The sector head comprises a sector mark located at the head of the sector and an address field.  This address field contains a track address, a sector address, and an error detecting and correcting code.          The index mark in the index field is detected, and the optical head is made to perform a jumping operation in response to the resulting signal, whereby the jumping operation is rendered certain.  When the address fields are being read, if some sector addresses cannot be read due to drop-out or for other cause, the signal produced by detecting the index marks are counted by a counter into which the signal produced by detecting the sector marks is clocked, for preparing the sector addresses.

Abstract: DATA TERMINAL AND SYSTEM FOR PLACING ORDERS     Abstract of Disclosure A pocket size data terminal is described for use by a large number of consumers in a system with which goods or services can be conveniently and automatically ordered.   A plurality of data terminals which can automatically dial a local processing center (LPC) are distributed among users each of whom can address the LPC with a unique user identification and an internal terminal identi-fication.  The terminal is internally battery powered.  Each data terminal can accumulate orders for goods or services in a send memory while the terminal is unencumbered by any external connec-tor. When subsequently connected to a phone line modular jack, upon command by a user  send memory contents are automatically sent to an LPC in a short burst.  The LPC verifies the use of the terminal, the authorization of the requested service and format of the data as well as other items as may be included in the order.   Upon verification, the LPC returns an appropriate message for visual display at the terminal and processes the order to suppliers of the requested goods or services.

Abstract: PROCESS FOR UPGRADING TAR SAND BITUMEN            ABSTRACT OF THE DISCLOSURE         A method for upgrading a concentrate of tar sands bitumen containing colloidal clay in which solvent-diluted bitumen is contacted for a short time in a riser with hot attrition-resistant substantially catalytically inert fluidizable microspheres, causing a selective vaporization of the lighter high hydrogen content components of the bitumen.          A portion of the heavier asphaltenes and most of the components which contain metals, sulfur and nitrogen remain on the attrition-resistant microspheres.  Colloidal clay in the bitumen feed also deposits on the microspheres instead of being carried over with the vaporized hydrocarbon product.  The contact material, with deposit, is passed to a burner provided with high velocity air jets which attrites the colloidal clay away from the microspheres and the material removed by attrition is recovered.  The heated microspheres are reintroduced into the riser for further contact with incoming diluted bitumen charge.

Abstract: ABSTRACT OF THE INVENTION     A method and device for data transmission over several parallel lines, in particular over optical fibers is described for transmitting measured values from a measuring station arranged at a high-voltage line to an evaluating electronic system at a high data rate, a high utilization of the available transmission lines, preferably optical fibers, is desirable.  To this end, via a clock line, clock messages are relayed which are separated from each other by a synchronization interval (P2) and which begin at least with a fixed clock message portion (PT), which may preferably be followed by a freely usable clock message portion.  The receiver recognizes each message start by the synchronization interval of the clock messages and forms during the fixed clock message portion synchronous sampling pulses, which may be followed by asynchronous sampling pulses for the duration of the free clock message portion.  The transmitter can now send via data lines data messages which begin synchronously with the fixed clock message portions and need not contain any fixed programmed pulses for the recognition of telegram messages.

An arm extends from the door and has an end captive for movement along the rail means.  The slidable member, the rail and the arm are constructed so that opening of the door, and the consequent arcuate motion of the captive arm end relative to the frame, is resolved into motion of the captive end along the rail means and sliding movement of the slidable first member against the spring means.  The spring thus urges the door towards its closed position.
